[0002] With the acceleration of the urbanization process and the continuous improvement of power infrastructure, cable connection equipment is increasingly widely used in the power system. Traditional cable connection equipment is usually fixedly installed and does not have the function of height adjustment, which has certain limitations in practical applications. For example, in the urban underground power grid, due to changes in ground facilities or maintenance needs, it is often necessary to adjust the height of the cable connection equipment; in temporary construction sites or industrial factories, the position of the cable connection equipment also needs to be flexibly adjusted according to the actual situation.

[0003] Due to the requirements of urban planning, the cable distribution box cannot be made too high. However, if it is made too short, in the event of urban waterlogging, if the water level is close to the wiring copper bar in the distribution box, it may cause safety hazards such as short circuits and electric leakage.

[0004] Most of the cable connection equipment on the market currently adopts a fixed structure. When the height of the equipment needs to be adjusted, it often requires manual disassembly and assembly, which is time-consuming and laborious, and is likely to cause cable damage or poor connection.

[0030] Referring to Figures 1 to 2 , a telescopic cable connection device includes:

[0031] A housing 100, buried underground, and the housing 100 is adapted for the cable to pass through;

[0032] A tap box 130, arranged above the ground, the tap box 130 is arranged corresponding to the housing 100, a wiring copper bar 120 is arranged in the tap box 130, a wire winding part 110 is arranged in the tap box 130, and the cable is wound around the wire winding part 110 and electrically connected to the wiring copper bar 120;

[0033] A lifting assembly, the tap box 130 is installed on the lifting assembly, and the relative height between the tap box 130 and the ground is adjusted by the lifting assembly.

[0034] By providing a housing 100 buried beneath the ground, cables can pass through the housing 100 without being disturbed by external forces, effectively avoiding the risk of cables being exposed and improving the safety of the cable connection equipment. The junction box 130 is mounted on a lifting assembly, which can be used to adjust the relative height of the junction box 130 to the ground. This design allows the junction box 130 to be quickly adjusted in height according to actual needs. In emergency situations such as urban flooding, the junction box 130 can be raised promptly to avoid the risk of short circuits or electrical leakage caused by excessive water levels. A winding section 110 is provided within the junction box 130, around which cables can be wound and electrically connected to the copper busbar 120. This design not only facilitates the organization and storage of cables, but also effectively reduces damage to the cables caused by pulling, thereby extending the service life of the cables. Adjusting the height of the junction box 130 using the lifting assembly simplifies the traditional manual assembly and disassembly process, reduces labor intensity, improves work efficiency, and reduces the potential for human error during cable connection.

[0035] The lifting assembly includes a ball screw and a lifting handle. The lifting handle is located inside the junction box 130. The ball screw is arranged in the height direction within the housing 100. The junction box 130 is movably mounted on the housing 100 via the ball screw. The junction box 130 drives the ball screw by rotating the lifting handle, thereby moving the junction box 130 up and down along the ball screw. The lifting handle is located inside the junction box 130. The operator can easily drive the ball screw by rotating the handle, moving the junction box 130 up and down along the ball screw. Compared with traditional manual disassembly or complex mechanical structures, this method greatly simplifies the operation process and improves work efficiency.

[0036] The ball screw has a trapezoidal or sawtooth thread. This self-locking feature automatically stabilizes the junction box 130 after it reaches a predetermined position, preventing spontaneous movement due to external loads or vibrations. This increases the safety and reliability of the equipment.

[0037] The lifting handle is connected to a first motor, which drives a ball screw to raise or lower the junction box 130. This motor-driven approach not only improves operational convenience but also enhances equipment safety.

The operator can drive the scissor structure 150 to expand or fold by rotating the handwheel 160, thereby driving the tap box 130 to rise or fall. This design makes the operation more intuitive and simple, and improves work efficiency.

[0039] The handwheel 160 is connected with a second motor. The second motor is in transmission connection with the handwheel 160, driving the scissor structure 150 to lift or lower the tap box 130. By driving the handwheel 160 with the second motor, the expansion or folding of the scissor structure 150 can be automatically controlled, thereby driving the lifting or lowering of the tap box 130. This design makes the operation more simple and efficient, reducing the complexity and labor intensity of manual operation.

[0040] The winding part 110 includes a winding shaft and a third motor. The winding shaft is suitable for cable winding. The third motor is in transmission connection with the winding shaft;

[0041] Among them, when the tap box 130 rises, the winding shaft rotates clockwise to relax the cable. When the lifting component descends, the winding shaft rotates in reverse to tighten the cable. The winding part 110 includes a winding shaft and a third motor. The third motor is in transmission connection with the winding shaft and can automatically manage the winding of the cable. This design makes the winding and unwinding of the cable more automated, reduces the need for manual operation, and improves operation efficiency. It can be understood that the third motor is selected as a motor that can rotate forward and backward, so as to control the winding shaft to rotate in different directions. The winding shaft is provided with a number of slots. The width of the slots matches the wire diameter of the cable. When the winding shaft rotates, it can clamp the cable more stably, avoiding the cable from sliding or falling off during the winding and unwinding process, thereby ensuring the stability and reliability of the cable during the winding process. The number and distribution of the slots on the winding shaft are adapted to the cable, avoiding accumulation or winding on the winding shaft. The edge of each slot is treated smoothly to prevent the cable from being damaged due to friction during long-term use. The depth of the slot is also optimized, which can not only ensure the cable is firmly fixed, but also will not damage the insulation layer of the cable due to excessive pressure.
